Description

Technical Field

[0001] The utility model relates to the technical field of integrated circuit mounting, and particularly relates to a supporting device for double-sided mounting of a multi-panel circuit. Background Art

[0002] A multi-panel circuit, also known as a circuit board panel, refers to arranging multiple circuit boards on a large-sized board to form an integral board combination, such as a circuit board panel with the Chinese patent publication number CN220326132U and a circuit board panel and a PCB single board with the Chinese patent publication number CN218103631U. The double-sided mounting process is to mount electronic components on both the top and bottom surfaces of the PCB board. This process is usually used in electronic products that require higher assembly density and more complex functions.

[0003] When the circuit board panel is too large, the circuit board panel will bounce when mounting components. Or the circuit board substrate bends after the first side is mounted and passes through the reflow soldering furnace. When mounting the second side, the circuit board panel is uneven, resulting in the inability to mount the components to the precise position. Currently, the double-sided mounting tray for the multi-panel circuit is a flat pallet. After the first side of the circuit board panel is mounted, the circuit board panel is directly flipped and placed above the pallet. However, the components mounted on the first side of the circuit board panel are uneven in height, and the circuit board panel is uneven, which affects the mounting accuracy of the second side of the circuit board panel and is also likely to damage the components mounted on the first side.

[0028] Embodiment 1

[0029] A supporting device for double-sided surface mounting of multi-panel circuits, as Figures 1 to 3 shown, is provided with a pallet 100, a base 200 for supporting the pallet 100, and a base 300 for fixing to an external device. The pallet 100 is assembled on the upper surface of the base 200, and the base 300 is liftably assembled at the lower part of the base 200; a plurality of component protection holes 110 are formed in the pallet 100, and the component protection holes 110 are distributed in a matrix, as Figure 4 . Four bases 300 are provided, and the four bases 300 are symmetrically distributed on the opposite sides of the base 200.

[0030] It should be noted that the function of the component protection holes 110 is that when the circuit board panel with the first-side surface mounting completed is placed upside down on the pallet 100, the components on the first-side surface mounting are located inside the component protection holes 110, and since the components do not come into contact with the pallet 100, the effect of protecting the components is achieved.

[0031] The base 300 is provided with a connection block 310, an assembly shell 320, a height adjustment nut 330 for adjusting the distance between the connection block 310 and the assembly shell 320, a magnetic block 340 and a spring 360 for adsorption with an external device, one end of the height adjustment nut 330 respectively passes through the connection block 310, and the height adjustment nut 330 is threadedly connected to the connection block 310, the other end of the height adjustment nut 330 is located inside the assembly shell 320, and the height adjustment nut 330 is rotatably connected to the assembly shell 320, the connection block 310 is fixedly connected to the base 200, and the magnetic block 340 is fixedly assembled to the assembly shell 320. The bottom of the assembly shell 320 is provided with a receiving cavity 350 for accommodating the magnetic block 340, and the magnetic block 340 is fixedly assembled inside the receiving cavity 350, and the assembly shell 320 is also provided with a through hole through which the height adjustment nut 330 passes, and the other end of the height adjustment nut 330 passes through. The two ends of the spring 360 are respectively in contact with the connecting block 310 and the assembly shell 320; the lower surface of the connecting block 310 is provided with a receiving groove 370 for receiving the spring 360, and at least a part of the spring 360 is located inside the receiving groove 370, such as Figure 5 .

[0032] The materials of the connection block 310 and the height adjustment nut 330 of the utility model are both non-magnetic metals; the materials of the support plate 100 and the base 200 of the utility model are also non-magnetic metals, and the non-magnetic metal of this embodiment is specifically aviation aluminum. It should be noted that the connection block 310 and the height adjustment nut 330 are non-magnetic metals to avoid the generation of magnetic attraction with the magnetic block 340, which facilitates the rise of the connection block 310. The function of the magnetic block 340 of the utility model is to perform magnetic attraction connection with external equipment of magnetic metal to avoid the entire multi-panel circuit double-sided mounting support device from tilting or shifting during operation. The function of the spring 360 is that when the height adjustment nut 330 is adjusted to move the connection block 310 upward, the spring 360 generates an upward force to facilitate the rotation of the height adjustment nut 330.

[0033] The base 200 is provided with a main body 210 and an extension arm 220. The extension arm 220 is integrally connected to the main body 210. The support plate 100 is located on the upper surface of the extension arm 220. The main body 210 is assembled with the base 300. A notch 230 for making way for external equipment is provided between the lower part of the extension arm 220 and the main body 210.

[0034] The extension arm 220 and the clearance gap 230 are used to avoid collision with external equipment, such as conveyor belts, mounting machine tracks and sensors, while allowing the pallet 100 to extend above the external equipment to facilitate the transportation of the circuit board panel to the pallet 100.

[0035] The supporting device for double-sided mounting of multi-panel circuits can place the circuit board panel that has completed the first-sided mounting flatly, and at the same time, it can also protect the components mounted on the first side. The supporting device for double-sided mounting of multi-panel circuits can also adjust the height between the base 300 and the base 200, so as to adjust the overall height of the pallet 100 and the base 200.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
